Abstract

Cosmetic or dermatological W/O emulsions contain (a) grapeseed oil (0.1-45 wt.% of total composition); and (b) one or more silicon emulsifiers.

Description

The present invention relates to cosmetic and dermatological preparations, in particular those of the water-in-oil type, processes for their preparation and their Use for cosmetic and medical purposes.

As the largest human organ, the human skin performs numerous vital functions. With an average surface area of around 2 m ² in adults, it has an outstanding role as a protective and sensory organ. The task of this organ is to convey and ward off mechanical, thermal, actinic, chemical and biological stimuli. It also has an important role as a regulatory and target organ in human metabolism.

Cosmetic skin care means primarily the natural function the skin as a barrier against environmental influences (e.g. dirt, chemicals, Microorganisms) and against the loss of the body's own substances (e.g. water, natural Fats, electrolytes) to strengthen or restore their horny layer to support the damage that has occurred in its natural regenerative capacity.

If the barrier properties of the skin are disturbed, increased absorption can occur toxic or allergenic substances or to infest microorganisms and as a result toxic or allergic skin reactions.

The aim of skin care is also to reduce the fat and fat caused by daily washing Compensate for skin water loss. This is especially important if that natural regenerative capacity is not sufficient. In addition, skin care products are said to exist Protect environmental influences, especially from the sun and wind, and skin aging delay.

Medical topical compositions typically contain one or more Medications in effective concentration. For the sake of simplicity, it becomes clean Differentiation between cosmetic and medical application and corresponding products to the legal provisions of the Federal Republic Germany referred (e.g. cosmetics regulation, food and drug law).

Emulsions are generally understood to be heterogeneous systems consisting of two there are no or only miscible liquids that can be mixed usually referred to as phases. In an emulsion is one of the two Liquids in the form of very fine droplets dispersed in the other liquid.

Are the two liquids water and oil and oil droplets are finely distributed in Water, it is an oil-in-water emulsion (O / W emulsion, e.g. Milk). The basic character of an O / W emulsion is characterized by the water. at a water-in-oil emulsion (W / O emulsion, e.g. butter) is that reverse principle, whereby the basic character is determined by the oil.

Of course, a multitude of possibilities is known to the person skilled in the art for stable W / O Formulate preparations for cosmetic or dermatological use, for example in the form of creams and ointments that range from room to Skin temperature are spreadable, or as lotions and milks in this Temperature range are more fluid. However, only a few know the state of the art Formulations that are so flowable that they would be sprayable, for example.

In addition, flowable preparations of the prior art frequently have the disadvantage that that they are unstable, on a narrow scope or limited The choice of raw materials is limited. Flowable products in which, for example, strongly polar Oils - like the vegetable oils commonly used in commercial products - are therefore not sufficiently stabilized on the market at the moment.

Products for the care of sagging, especially aged skin are known per se. They contain e.g. B. retinoids (vitamin A acid and / or their derivatives) or vitamin A and / or its derivatives. However, their effect on structural damage is limited in scope. In addition, there are significant ones in product development Difficulty getting the active ingredients to a sufficient degree against oxidative decay stabilize. The use of products containing vitamin A acid determines this often severe erythematous skin irritation. Retinoids are therefore only minor Concentrations can be used.

Often, the sagging skin is also a side effect of the Obesity and / or the so-called cellullite associated with it.

The body awareness of consumers has been clear in recent years gone up. In addition to cleaning and care applications Measures increasingly taken to improve the body silhouette. The cellulite - a widespread phenomenon - occupies a central position. The visible Image of cellulite is due to an increase in fat deposits in the subcutis (Subcutaneous fat tissue), a weak connective tissue as well as a reduction of the Flow conditions in the blood and lymph channels. The cause is therefore partly Plant-related weakening of the connective tissue with the simultaneous appearance of enlarged fat cell chambers due to obesity, unbalanced nutrition, Lack of exercise. The development of cellulite can also increase Permeability of the hair vessel walls can be attributed to the penetration of water into the Connective tissue allowed.

In addition, there may be a local lack of testosterone on the affected skin areas consist. Anyway, cellulite is a phenomenon that almost never occurs in men watch is.

The object of the present invention was therefore to find ways which have the disadvantages avoid the state of the art. In particular, it was a task of present invention to provide formulations which are advantageous tightening can cause sagging skin.

Oils and fats differ among other things in their polarity, which is difficult to define is. It has already been proposed to compare the interfacial tension To take water as a measure of the polarity index of an oil or an oil phase. It applies that the polarity of the oil phase in question is greater, the lower the Interfacial tension between this oil phase and water. According to the invention interfacial tension is considered a possible measure of the polarity of a given oil component.

The interfacial tension is the force that is at an imaginary, in the Interface between two phases located line of length of one meter acts. The The physical unit for this interfacial tension is classically calculated the force / length relationship and is usually divided into mN / m (millinewtons) Meters). It has a positive sign if it endeavors to do that Reduce the interface. In the opposite case, it has a negative sign.

It is particularly advantageous to do the oil phase of the preparations according to the invention in this way to design that they predominantly from non-polar to medium-polar oils Interfacial tension of 20 to 45 mN / m exist, or that the total polarity the oil phase lies in the interfacial tension range of 20 to 45 mN / m.

According to the invention it is possible to use a certain proportion of polar lipids in the Tolerate lipid mixture, but this proportion should never exceed 25% by weight preferably less than 15% by weight and ideally should not be more than ≤ 10% by weight, based on the total lipid phase.

Table 1 below lists medium-polar lipids which are advantageous according to the invention as individual substances or as a mixture with one another. The relevant interfacial tensions against water are given in the last column. However, it is also advantageous to use mixtures of higher and lower polar and the like, provided that it is ensured that the overall polarity of the oil phase is in the range claimed. Table 1
